urllib2使用代理服务器详解编程语言

本代码演示了python的urllib2模块如何使用代理，以及需要登录验证的proxy

# The proxy address and port: 

proxy_info = { host : proxy.myisp.com, 

 port : 3128 

# We create a handler for the proxy 

proxy_support = urllib2.ProxyHandler({"http" : "http://%(host)s:%(port)d" % proxy_info}) 

# We create an opener which uses this handler: 

opener = urllib2.build_opener(proxy_support) 

# Then we install this opener as the default opener for urllib2: 

urllib2.install_opener(opener) 

# Now we can send our HTTP request: 

htmlpage = urllib2.urlopen("http://sebsauvage.net/").read(200000) 

#如果代理需要验证 

proxy_info = { host : proxy.myisp.com, 

 port : 3128, 

 user : John Doe, 

 pass : mysecret007 

proxy_support = urllib2.ProxyHandler({"http" : "http://%(user)s:%(pass)s@%(host)s:%(port)d" % proxy_info}) 

opener = urllib2.build_opener(proxy_support) 

urllib2.install_opener(opener) 

htmlpage = urllib2.urlopen("http://sebsauvage.net/").read(200000)
